 Steps:
 
-1. Download the config and genesis files. You need to have [genesis.json](https://github.com/binance-chain/smart-chain-binary/blob/pre-release/bsc/fullnode/config/genesis.json) and [config.toml](https://github.com/binance-chain/smart-chain-binary/blob/pre-release/bsc/fullnode/config/config.toml)
+1. Download the binary, config and genesis files from [release](https://github.com/binance-chain/bsc/releases/download/v1.0.0-alpha.0/binary.zip), or compile the binary by `make geth`. 
 2. Init genesis state: `./geth --datadir node init genesis.json`.
 3. Start your fullnode: `./geth --config ./config.toml --datadir ./node`.
 4. Or start a validator node: `./geth --config ./config.toml --datadir ./node -unlock ${validatorAddr} --mine --allow-insecure-unlock`. The ${validatorAddr} is the wallet account address of your running validator node.
